DUMPING WAGON.

Application filed April 26, 1920. Serial No. 376,599.

T0 all @l1/0m t may Concern.'

Be it known that l, Cin-intrus N. Ceann, a citizen of the United States, residing in domerville, in the county oi' Middlesex and State ol Massachusetts, have invented an .improvement in lumpin livagons, oit which the following,` description, in connection with the aceompanying drawings, .is a specitication, like characters on the drawings representing like parts.

This invention relates to a wagon for transporting and discharging' coal, gravel and like material.

The invention is herein shown as embodied in a horse drawn Wagon to which it is particularly applicable. The invention has for its object to pr vide a Wagon with which the load oi? coal or other material can be transported and delivered by basket with a single operator, in a nriniinumI time and with a minimum loss'oftl coal or the like, an d without imposing on the horse extra duty as will be described.

To this end the wagon body. which. may be the body of the ordinary horse draWi'i Wagon, is normally supported upon springs, is pivotally mounted so that its :Front end can be elevated and is provided with an elevating mechanism which is carried by the Wagon body and is normally moral-,ile there- With under the .influence oi? said springs to permit the latter to function, and is capable of being` firmly supported when it desired to tilt the Wagon body on its pivot.

The Wagon body is 'further provided at its rear end with means ttor preventingloss oi .inat-erial, and. with means 'for supporting a basket or like receptacle while the latter is being filled, and for elevating` the lilled basn into a convenient 'position ,for the operator to handle.

These and other features olf this invention will be pointed out in the claims at the end of this speciiication.

F l is a side elevation oit a suiiicient portion oi? a horse drawn Wagon embodying this invention to enable the latter to be understood.

Fig. 2 is a like vieuT with the Wagon body tilted into its dischinging position.

Figs. 5%, i and details oiI the mechanism ttor elevatingv the iront end ot the Wagon body.

Figs. 6, Y, 8 and 9, details ot the rear end ot the Wagon body to be referred to, and

Fig. l0, a detail to be referred to.

Referring to the drawings, l() represents the body portion of a horse drawn Wagon, which latter may be of any suitable or usual construction except will bediereinatter pointed out. y

The body l0 normally supported as herein shown by a transverse. iront springl l2 and by longitudinally extended rear springs i3, which springs are supported by the 'front and rear axles lo, i6, as common in Wagons of this character. The axle-s l5, l@ are connected by a perch 17.

The Wagon body iO is pivotally mounted so as to be tilted into an inclined position, and in the present instance it is pivotally mounted on the rear' springs lil and has its front end detachably mounted on the itrcnt springv l2. In the present instance the rear springs i?, have their upper halves connected by a cross bar 1S to which the body l0 is connected by hinges, only one oit which is shown in l and 2, one member 19 of which is fastened to the cross bar 18 and the other member 20 to a metal plate 2i attached to the underside of the body l0. The trent end oi the body 10 isl engaged with the iront spring i2 by a pairot clips or devices, here in shown two angle irons 22, 23 which are secured to the body l0 and are arranged to straddle the iront spring` l2 and thus eticotively connect the iront end oi? the body to said spring under normal conditions of use, as represented in Fig. l, but which are capable oi being disengaged 'from said :iront spring when the iront end oi" the wagon body is elevated to tilt the latter as shown in Fig. 2.

Provision is made ior tilting' the Wagon body by mechanical means, arial to provide a solid support tor said tilting` means While the Wagon body is being tilted, and to provide for vmovement ot the tilting' means With the Wagon body, so as not to restrict or interfere with. the movement of the front and rear springs under normal conditions ot use.

rihe lifting means is preferably made as herein shown and comprises a threaded rod or screw 25 havingV its lower end mounted to turn in a bearing; 26, see Fi Il, pivotally secured by a pin or bolt 2T with a base plate or block 28 having ears 29 which support the pivot nin Q7. he base plate or bloc r 2S is bodily movable vertically and is hereinshown guided in such movement by pins or rods 30. erected from a plate 3l which is secured to the underside of the perch. 17,

which latter is shown in Fig. si as provided with an opening 32 extended through it and oi' sui'licient size to receive the base block 26.

rlhe upper end of the threaded rod or screw is engaged with an internally screw threaded hub or nut 33, which is aiiixed to the wagon body 16 to move therewith and is pivotally mounted to permit the screw rod 25 to remain substantially vertical. while the wagon body is being raised and inclined. The nut is provided as shown in Fig. B

`with laterally extended hollow bosses 341-.,

into which, are extended pivot `pins B6, 37 which are supported by the 'forked arms 38 et a. yoke shaped piece 3S), `fastened to a cross bar "O on the underside oit' the wagon body. The pivot pins 36, 3T are secured to bars Lil, attached to the cross bar t0 and to a cross bar i3 parallel "'th it. The upper end of the screw or threaded rod 25 is non inally extended onto the wagon body through a suitable opening in the floor there of, and said openinga is protected by a suitable hood dei indicated by dotted lines in lligs. 1 and 2, which prevents escape oiE the coal or other material through the said openlhe threaded rod or screw 25 is rotated from a. shaft 115 by a bevel pinion 16 meshing with a bevel gear i7 mounted on the screw or threaded rod 25 to turn therewith.

The shaft is represented as turned by hand and is supported in bearings 48, 119, which are supported by the bearing 26 and are respectively attached thereto ,by the brackets or arms 50, 51.

By reference to Figs. 1 and 2, it will be seen, that when the wagon body is in its normal condition or position and loaded with coal or similar material, the shaft i5 can be turned so as to rotate the screw 25 and cause the latter to travel up through the nut 33 a su'Hicient distance to raise the block or base plate 26 away 'trom the supporting plate 31, as represented in Fig. 1. l'lilhen in this position, the load is carried by the springs 12, 'i3 in the saine manner as in the ordinary horse drawn coal wagon. The-'n the wagon reaches the house or other place where the coal is to be delivered, the operator turns the shaft 45 in the opposite direction to lower the screw until the base block 28 has been lowered into engagementwith the supporting plate 31, and on the centinued turning.;` movement ot the screw rod 25, the nut will travel up on the screw rod and elevate the front end of the wagon body and turn the latter into an inclined position as shown in 2. The wagon body may be secured in its inclined position or in its .normal position by a device tor locking` the shaft l5 from rotation. The locking` device is shown as a forked metal piece 55, see Figs. 4 and 5, which straddles a square portion 56 ot the hub ot the bevel 1 ,enanas pinion 46 and is made of su'iicient length to engage the arm 50 oi2 the bearing member -S for said shaft.

lllhen the wagon body is in its inclined or discharging` position7 the coal may be discharged into a basket or receptacle through the usual. opening in the tail board, which is normally closed by a suitable slide 61, see F ig. 7, and such as now commonly used on tail boards et coal wagons. The tail board may be made as a single piece but is herein shown as composed of upper and lower members or halves 652, 63, which are connected together by suitable hars or rods (Si extended through metal eyes aiiixed to said members, or in any other suitable niianner. The lower member El will be provided with the opening through which the coal may run into the basket 60. rllhe t2 'l board has attached to it a supporting inember tor the basket, which supporting member, asshown in Figs. 1 and 2, consists of a platform 67 supported at its opposite sides' by parallel links 68, 69, which are pivoted to said platform at their lower ends and at their upper ends to brackets or arms 70 pivotally secured to lugs or ears 200 on the tail board, and it desired also supported at theiil outer ends by chains or like devices 71 from .metal eyes T2 aitnred to the member 63 of the tail board.

Provision is uiade for elevating the basket when loaded, up into a position where it can be conveniently handled by the operator. r.llo this end, the supporting member 67 ij' connected with a windlass carried by the tail board. The windlass referred to coinprises as shown a rotatable shaft 75 supported in bearings 76 aiiixed to the upper member ot the tail board and chains 77, or the like, fastened at one end to the shaft 75 and at their other ends to the supporting member 67. The shaft T5 is provided with a crank 7S, by turning which the operator can wind up the chains 77 and lift the supporting member 6'4" with the loaded basket or receptacle 60 thereon, from the position shown in Fig. 2 into that shown in Fig. 6, and can retain said platform in its elevated position by engaging a pawl 8() with a. ratchet wheel 81 on the shaft 75. When the basket has been elevated, it can be more conveniently handled by the operator and is in a position to be easily transferred to his back. By disengaging the pawl 80, the supporting member 67 may be lowered into its normal position shown in Fig. 2. Then the supporting` member 6T is raised from its lowered position into its elevated position, the inner link 69 passes by the outer link 68 and to enable this to be done said links are made as shown in Fig. 16, wherein the inner link 69 is shown provided with a boss 88 at its lower end and the outer link 68 is provided with a boss 8e2 at its upper end. The

boss 811 holds the lower end ofthe outer link G8 away from the platform 67 and the boss 83 holds the upper end of the inner link 09 away from the bracket 70, which permits the links 68, 09 to pass by each other When they are moved from the position shown in F ig. 2 to that shownin Fig. 6 and vice versa. y

The brackets are pivoted to the tail board so as to move in a vertical plane, which is of advantage, for When the basket 60 is not on the platform 67, the vvindlass can be operated to bring the platform 67 near to the tail board, Which is permitted by f pivotin the brackets '70 to the tail board l y as described. Allt-Will thus be seen that when not in `use the basket hitting mechanism can be brought close up to the tail board wout of the Way,in which position it is held by the pawl 80. Furthermore by attaching the brackets 70 to the tail board, the latter can` be dropped down in the usual manner when desired, Without interference with its movements by the lifting mechanism.

The tail board is pivoted to the rear end of lthe wagon body 10 and provision is` made for preventing loss of coal and especially soft or tine coal passing out between the tail board and the bottom of the 1wagon. To this end, the member G3 of the tail board is pivoted to the bottom of the body portion 10by means of a hinge composed of a sheet metal mem-- ber 100 extended the Width of said body portion and preferably set into a recess 101 in the bottom of the body portion to have its upper surface flush With the upper surface of said bottom, and a sheet metal member 102 secured to the inner face of the member 63 of the tail board.

The sheet metal members are provided n'fith hollow bosses 103, 104- Which receive the pintle or pivot rod 105, and said bosses are fitted substantially tight, so as to malte a relatively close 'joint and prevent soft coal or other fine contents of the Wagon passing between the bottom of the body portion and the tail board 'when the latter is in its horizontal or open position shown in Fig. 8. The member G3 of the tail board may also have attached to it curved side pieces 106 to prevent the coal dropping olf from the sides of the tail board when the latter is in its horizontal position shown in Fig.

Provision is made for relieving the rear springs from strains placed upon them, es-

pecially under the influence of the loa-d, when the Wagon body is in its horizontal position and the Wheels of the Wagon strike an obstruction, and also when the Wagon body is in its downward and rearwardly inclined discharging position.

ln the present instance, one arrangement or construction is shown for accomplishing this result, which consists of a stationary upright member 110 supported by the perch 17, and a movable member which connects the upright member 110 with the rear portion ofthe Wagon body, and in the present instance with the cross bar 18 attached'to the rear springs 13. 'The movable member referred to, is shown as threaded rods 112, 113, `adiustably connected by a turnbuclrle 11d, and linlrs 115, 116, connecting said rods with the stationary member 110 and with an eye-bolt 117 attached to the cross bar 18. By reference to Fig. 1, it will be seen that if the rear Wheels of the Wagon should strike the curbstone in backing or an obstruction in the road, movement of the wagon body .in the direction of its length With rela tion to the rear axle, is resisted by the connection between the cross bar 18 and the upright member 110, and when the Wagon body is in its inclined or discharging position shown in F ig. 2, movement of the Wagon body in the direction of its length under the influence of the load, is resisted in the same manner.

llhemovable connection or' member acts as a lever, which is pivoted to the upright 110, so that the end connected with the eyebolt 11'? moves in the arc of a relatively .large circle and therefore allows of but slight longitudinal movement of the Wagon bodv When the connection or member passes from above the horizontal radius to below the same and vice versa.

is aresult excessive strains on the rear springs and on connections with the rear axle are avoided or at least reduced to a minimum.
